Glacier fluctuations in the Strait of Magellan tell of the climatic changes that affected southern latitudes at 53-55°S during the Last Glacial Maximum (LGM) and Late-glacial/Holocene transition. The AA. present a revised chronology based
Argentina ; C 14 dating ; Climatic change ; Deglaciation ; Geochronology ; Glacial features ; Glacial lake ; Palaeogeography ; Patagonia
features of the area are 3 shorelines created by ice-dammed lakes that drained eastwards to the Atlantic. The chronological implication is that late-glacial changes in southern Patagonia were under the influence of the Antarctic realm and out of phase
The AA. concentrate on one site, Puerto del Hambre, a key location for reconstructing palaeoenvironmental change in southernmost South America. They report geomorphological, structural geological, seismic and topographic data that all show the site
